Chase admitted he thought he might be able to swing a kiss on the cheek from the pop superstar. Even after Underwood told him that her husband was in the building somewhere, he asked for the real thing.

“How are we going to do this?” Underwood asked him.

“Lip to lip,” Chase responded.

And the singer gave Chase his first kiss right on the lips.

The phrase “lip to lip” is catching on. Underwood used #liptolip to personally tweet Chase after the show.

The 12-year-old said he didn't pay much attention to the show after the kiss and he’s overwhelmed by the attention he received afterward. He said about 100 people approached him after the concert and asked to have their pictures made with him.

Chase’s birthday is coming up later this week, and he’ll spend it in New York City making the rounds of network morning and talk shows.

His favorite Carrie Underwood song? "Blown Away." Exactly how he’s feeling in the aftermath of a memorable first kiss.
